Although Phyllome OS would like to support as many operating systems as possible, it will mainly focus on modern, UEFI-compatible operating systems that are shipping with at least some support for `virtio` devices.
As of today, without accounting for Linux distributions, there are dozens of production-ready operating systems. There are two families of operating systems that dominate this space, the Unix family and the Windows family. Everything else will be categorized as independent.
> *Support for guest systems differs widely. In general, free and open-source operating systems such as Linux distributions are better supported than proprietary operating systems*.
